This release brings about a new feature for PS Vita Standalone installations to maximize the amount of storage space you can use simultaneously.
We achieve this by enabling PSP Go's "ef0" (Internal Memory) and redirecting it to PS Vita's uma0:pspemu/, while leaving the original mapping of ms0 to ux0:pspemu/ intact, allowing both devices to be accessed at the same time.
Because ARK already has very good support for PSP Go's Internal Memory (ef0), it was fairly simple to remap that device to use on PS Vita, this however requires manually installing a new taihen plugin.
The new plugin needed to get ef0 working on PS Vita is aptly named ef2uma.suprx and can be found inside the PS Vita folder, it can be enabled on both of the Standalone bubbles ARK and ARK-X (NPUZ01234 and SCPS10084).
Note 1: It has not been implemented in Adrenaline since it already has its own device mapper that might conflict with this one.
Note 2: The plugin is totally optional and without it the behavior will be the same as it's always been.
The update also contains some small fixes, code cleanup and refactor (Stability Improvement!!!).
*b: updated with fix that would prevent from creating saves on ef0.
*c: fixed rebooting into recovery & GAME150 patch and icon fix 1.50 ARK-4 CFW
